Thermoplastic materials are often applied by heating a part and then putting it into a fluidized bed of powder, Aziz. The usual pretreatment for steel is iron or zinc phosphatizing. Some good books on phosphatizing are Samuel Spring's Preparation of Metal for Painting ⇦[this on on Amazon affil links] and "Phosphating of Metals" ⇦[this on Amazon or AbeBooks affil links] by Rausch. Some good ones on powder coating are Roger Talbert's "Powder Coating" [available from Chemical Coaters Association Int'l] and Bob Utech's Guide to High Performance Powder Coating [on on Amazonaffil links]. Good luck with your study!
